it does absolutely nothing. The man looks down at Bakugou, dead in the eye-and just grins, showing his fangs.
"Hf-"
Erick kicks and struggles against him
"Nnn-LET GO ASSHOLE!! TELL YOUR BOSS I DON'T WORK FOR HIM ANYMORE!!"
???: "Heh...as long as you're marked, you're still one of us...you know how this works. Unless you want a nice, shiny stake through the heart-"
"F-FUCK OFF!"
???: "Now hold still-we'll be back home in a minute-"
Erick bites him
???: "GAH!"
His grip loosens but not fully. He laughs a little
???: "You little shit-"
Erick falls to the floor
"Oof-"
He quickly recovers and gets up, running over to Bakugou and taking a defensive stance next to him, baring his fangs at the guy
???: "Tch. Not like it matters much anyway. If I don't get you...one of the other's will."
In a swirl of shadow, the guy disappears
